Amfani da Turanci na Aiki ko Amfani da Turanci Ideal

Wani ya OP Amp Ideal?

Amfani da operational amplifier (OP Amp) shine ni amfani da direct current voltage amplifier. Yana zama, yana sanya voltaji na input wanda ke tafi shi. Input resistance na OP amp yana bukatar saukar, amma output resistance yana bukatar kadan. OP amp zai yi kyau a kan open loop gain mai sauƙi. A cikin OP amp ideal, input resistance da open loop gain suka zama infinity, amma output resistance suka zama zero.

OP amp ideal na da abubuwa masu alamar:

Saboda haka, ideal op amp shine define a matsayin, differential amplifier tare da open loop gain infinity, input resistance infinity da output resistance zero.

Ideal op amp ba da input current. Wannan shine saboda input resistance infinity. Saboda input resistance na ideal op amp infinity, akwai circuit mai duka a input, saboda haka current a duka input terminals shine zero.

Ba da current na input resistance, ba za a samu drop na voltaji a bayan input terminals. Saboda haka ba za a samu offset voltage a bayan inputs na ideal operational amplifier.

Idan v1 da v2 suna voltaji na inverting da non-inverting terminals na op amp, da v1 = v2 a cikin ideal case,

Bandwidth of operation na ideal op-amp shine infinity. Yana nufin cewa op-amp yana taimakawa a duk frequency ranges na operation.
